About library

Proxying calls to any functions to retrieve data from the cache.

• Installation
• Using

Installation

Run command:

composer require mima/cache-proxy

Add dependency on your composer.json:

{
    "require": {
        "mima/cache-proxy": "~1.0"
    }
}

Using

• Update cache and retrieve data
• Flush data from cache

Update cache and retrieve data

Create new instance of CacheProxy\Proxy class:

use CacheProxy\Proxy;
use CacheProxy\Adapter\DoctrinCacheAdapter;

$adapter = new DoctrinCacheAdapter($doctrinCacheInstance);
$cacheProxy = new Proxy($adapter);

The adapter should implement the interface CacheProxy\Adapter\CacheAdapterInterface. It is used to adapt the interface to caching in your framework.

You can use one of several prepared adapters or create your own:

• CacheProxy\Adapter\DoctrinCacheAdapter implementation for doctrine cache
• CacheProxy\Adapter\YiiCacheAdapter implementation for yii2

Use instance of CacheProxy\Proxy class in your code as it is:

use MyNamespace\AnyClass;
use CacheProxy\Target\ProxyTarger;

$object = new AnyClass();
$target = new ProxyTarget([$object, 'anyMethod'], ['arg1', 'arg2']);

$data = $cacheProxy->proxyTarget($target);

Or you may create decorator for your class and depend him from CacheProxy\Proxy class:

namespace MyNamespace;

use CacheProxy\Proxy

class AnyDecorator
{
    /**
     * @var AnyClass
     */
    protected $class;
    /**
     * @var Proxy
     */
    protected $proxy;

    public function __construct(AnyClass $class, Proxy $cacheProxy)
    {
        $this->class = $class;
        $this->cacheProxy = $proxy;
    }

    public function anyMethod($arg1, $arg2)
    {
        $target = new ProxyTarget([$this->class, 'anyMethod'], func_get_args());

        return $this->cacheProxy->proxyTarget($target);
    }
}

Key for caching data generated on runtime in CacheProxy\Proxy class. If you want specify any suffix for cache key, pass second argument to CacheProxy\Proxy::proxyTarget method.

$cityId = 1;
$cacheProxy->proxyTarget($target, $cityId);

To set the ttl for storing data in cache, pass third argument to CacheProxy\Proxy::proxyTarget method.

$ttl = 3600;
$cacheProxy->proxyTarget($target, null, $ttl);

Flush data from cache

If you want remove all cache data, do as shown below:

// this code update cache ad return data
$key = md5('any-key');
$cacheProxy->proxyTarget($target, null, $ttl);

// this code flush all data from cache by target and key
$cacheProxy->flushTarget($target, $key);
